In addition to selected national microfilm records, this branch includes original regional records from Northern California, Hawaii, Nevada (except Clark County), the Pacific Trust Territories, and American Samoa. This branch of the National Archives holds more than 40,000 cubic feet of original historical records dating from 1850 to the present. The original records include photographs, maps, and architectural drawings relating to regional history, and include subjects such as gold mining, Native Americans, Chinese immigrants, and regional court records, including naturalizations. Among their national records on microfilm are U.S. census records for all states from 1790-1920, excluding 1890; census records indexes for 1880, 1900, 1910, and 1920; Native American and Samoan censuses; and various military service records, and pension and bounty land warrant applications.

Access to Records

On Site

Researchers who plan to use the original records on-site should schedule visits in advance. All researchers using original records need to get a researcher ID card. Records may be photocopied unless the condition of the document prohibits it. Researchers who plan to use the microfilm records can do so in the self-service microfilm reader room. No appointment is necessary but there is a time limit for use of the readers when other researchers are waiting. Self-service microfilm to paper copies are available.

Through the Mail

The National Archives staff will not do genealogical research for you. However, they can look up and copy a particular record if you have detailed information about that record. Costs are usually less than $10. If you are looking for a specific type of record, call or write to find out what information is required before the staff will initiate a search.
